It's a fast-paced 2-6 player combat game (1v1, 2v2, 3v3, 2v2v2, or free-for-all). Select from a variety of heroes that play and feel completely distinct from one another. Attack opponents and activate abilities by rolling your hero's unique set of five dice. Accumulate combat points and spend them on cards that have a large range of effects, such as granting permanent hero upgrades, applying status effects, and manipulating dice directly (yours, your teammate's, or even your opponent's).
One game of Honshu lasts 12 rounds, and each round is divided into two phases. First, Map cards are played in a trick and the player who played the highest value card gets to pick first from those played. Then the players use the Map cards picked to expand their personal maps. Each player must expand their personal maps to maximize their scoring possibilities.
Manipulating your position in the player order is crucial for mastering Honshu!
*Not actually millions of combos ... but like thousands or more, maybe.
